Xia Hongsheng and the three of them followed the old man and hurriedly walked to a thatched cottage, and as soon as they arrived at the door, they saw that there were mosquitoes all around. The little mosquitoes after the autumn bite people the most, and they bite people the hardest, and they can't jump for many days. In front of the grass hall of the three of them, the floaters immediately buzzed and flew over, but turned around and flew away.

"Let's not talk about anything else, let's get wormwood to smoke and repel mosquitoes." Xia Hongsheng looked left and right, and then said: "There are so many autumn floaters here, if you don't expel them, you will have to be infected in a few days." ”

After finishing speaking, the imperial doctor ordered Sun Simiao to look at each other, and then asked people to go and get wormwood. The three of them waved their hands and drove away the floaters while entering the grass hall.

After entering, I saw a child lying on the bed, wrapped in a quilt that had been wrapped several times, and he was still shivering there, crying cold.

Sun Simiao hurriedly walked over, not shying away at all, and pulled the little child's hand out of the quilt when he went up, and then raised his hand to take the pulse. The Imperial Physician Ling stood aside, while Xia Hongsheng kept waving the medicine cloth bag full of wormwood in his hand to drive away the surrounding floaters. Soon, Sun Simiao let go of the child, put his arm back into the quilt, and leaned over to break his eyes to see. The child's consciousness was already blurred, and he only subconsciously shouted cold in his mouth.

Sun Simiao stood up, turned around and nodded at Imperial Doctor Ling and Xia Hongsheng.

"Sun Daochang, if you have malaria, how is it usually treated?" Xia Hongsheng looked at the child on the bed, and then asked.

"Between the ages of one year, they are similar in age. Or dye when walking. It turns into cold and heat. The name is plague malaria. Cover is caused by feeling malaria, with cold and heat, with a fixed time, mostly in summer and autumn, also known as miasma or miasma, easy to offend the mind, so that the human body yin and yang are extremely prevalent. Hearing Xia Hongsheng's question, the imperial physician Ling explained beside him: "Therefore, malaria is treated." The basic principle of treatment should be to dispel evil and intercept malaria. According to the different symptoms, it can be treated by reconciling the surface and the inside, clearing away heat and protecting Jin, warming the yang and reaching evil, clearing the heart and opening the body, dissolving turbidity and opening the body, and nourishing qi and blood. ”

"Not bad." Sun Simiao nodded: "It's a pity that although the world uses this method as a cure for malaria, the effect is not good." I got malaria and still died. ”

The Imperial Physician Ling said a lot. Xia Hongsheng didn't understand, but he knew in his memory that Artemisia annua had artemisinin in it. This thing can cure malaria. I saw it on the news at the beginning, and I won the Nobel Prize in Medicine for this discovery, and it must have really worked.

So Xia Hongsheng said: "I can be sure that Artemisia annua can treat malaria, Sun Daochang, Lord He, since the current method has no effect, it is better to try to treat Artemisia annua, and use dead horses as live horse doctors!" Artemisia annua is also a heat-clearing but evil herb, even if it cannot cure malaria, it will not have any bad effects. ”

Sun Simiao and the Imperial Doctor ordered the two to look at each other, and the two of them had no other way. Since Yongzhou invited them to treat malaria, it has already taken all the energy to keep malaria from spreading out of the village, and nearly half of the people infected with malaria in the village have now died. Fortunately, this village is on the top of the mountain, and there are no other villages around, so it has not spread for the time being. If this place is lost and malaria goes out of the village, it will become an epidemic and need to be reported to the emperor. So apart from trying Xia Hongsheng's method, the two of them really have no other way.

"Good! Then try Xiahou's method! Sun Simiao nodded and asked, "How to do it, please ask Xiahou to command!" ”

"It's not complicated, Artemisia annua, you have to let him drink it." Xia Hongsheng thought for a while and said, "I remember that I need to drink it......"

After listening to Xia Hongsheng's words, the imperial doctor ordered him to shout outside: "Come on, quickly go and see the Artemisia annua brought to boil!" ”

Boiling? Xia Hongsheng scratched his head, remembering that it seemed that he had drunk it cold, and he didn't seem to have survived it, right?

"Wait......" Xia Hongsheng scratched his head and recalled vigorously: "I don't think it's tormented. It's raw...... It seems to be rubbing out the liquid in Artemisia annua...... I remember that it hadn't been boiled, and it was obviously raw, and it smelled grassy! ”

"That's the stain." Sun Simiao listened to Xia Hongsheng's words and said, "It was concocted by the staining method. Soak Artemisia annua with a little clean water, wait until the Artemisia annua is soaked, and then rub the juice vigorously into the water and take it orally. ”

The imperial physician ordered people to boil the water immediately, and after boiling, put the kettle into the copper basin, and pour cold water into the copper basin to speed up the cooling.

When the hot water in the kettle was completely cool, the imperial doctor ordered him to wash his hands, personally pressed the Artemisia annua into the water and soaked it, and soon soaked the Artemisia annua, then grabbed a handful of Artemisia annua with both hands and took it out, replaced it with a clean bowl and placed it underneath, and then twisted the Artemisia annua in his hand with both hands as if wringing out a towel. Immediately, I saw that dark green juice was wrung out of the Artemisia annua, and the Imperial Doctor ordered to continue to twist it vigorously, and finally a bowl of dark green Artemisia annua juice was crowded.

Sun Simiao saw that the imperial physician order was crowded with a bowl, so he immediately went over and served it, tasted it without saying a word, took a few sips, and then brought it to the child, sat down and carefully fed him.

After Sun Simiao fed the child a bowl, the imperial doctor had already wrung out another bowl, and Sun Simiao took it and fed the child all of them.

After that, the three of them sat down in the room and waited for Artemisia annua to take effect on the child.

The wormwood outside was on fire, the smell of wormwood spread, and there was a buzz around, and floaters were flying all over the sky.

"By the way, Xiahou, you just said that you came to me today to discuss something, but I don't know what it is?" While waiting, Imperial Physician Ling suddenly remembered what Xia Hongsheng had just said, so he asked.

"Alas, I was going to discuss it with the two of you, and I wanted to go and ask His Majesty for something." Xia Hongsheng said: "It's about patent protection. Because of one thing, I suddenly thought of why our people in Datang always hide what they have skills that others don't know, a certain skill, or a certain prescription or something, for fear that others will know, and would rather take it into the grave and let it be lost than learn it from others. What's the good of that, because in the long run, more and more things will be lost, and many good things will disappear, which is not right. After thinking about it, I feel that the root cause of this phenomenon is the lack of a perfect patent protection system. ”

"Patent protection?" The two were stunned and looked at Xia Hongsheng in confusion.

Xia Hongsheng explained to the two: "The so-called patent refers to exclusive interests and rights. It is said that whoever discovers a certain technology through painstaking study has the exclusive right to this technology. Let's take an analogy, a certain Lang Zhong worked hard all his life, and he finally found a cure for a certain disease. There is no one else in the world who can cure this disease except him. He was poor, he ate the last meal without the next meal, thinking that he hoped to use this recipe to make his life better. But there was another man who stole this recipe from him, and then went out and boasted that he could cure this disease, and that he had developed it himself. He stole the fruits of that Langzhong's labor, and he gained fame and benefits, but what about Langzhong, who had really studied this recipe? continued to be destitute, and came out to argue a few words, but was falsely accused that he had copied the man's recipe. Hungry and cold, he was extremely angry, and before he died, he admonished his son that if there is something like this prescription in the future, he must not let outsiders know about it. This is the consequence of the absence of patent protection. ”

The two nodded, and Xia Hongsheng continued: "Imagine that if our Datang can have a set of laws to protect this exclusive right, through the law, it is stipulated that those who invent certain things will have the exclusive right to this kind of thing, and if others steal it without consent, it will be illegal and need to be heavily punished." If others want to use the technology legally, they must obtain the consent of the inventor of the technology and pay a fee to the inventor of the technology and obtain authorization before they can use it legally. In this way, if you put it on the example just now, that person will not dare to steal Lang Zhong's recipe again, and Lang Zhong will not suffer losses because of this. If others want to use that formula, they must get Lang Zhong's consent before they can use it freely, but they can't impersonate themselves and say that they did it. In this way, Lang Zhong will be guaranteed to receive benefits from this recipe, and he will no longer conceal this recipe, and the more people who use this recipe, the more fame and fortune he will get, so not only will he not hide it, but will generously let people know that he has a cure for this disease. And in order to get more benefits, he will go to study other prescriptions, and other Langzhong will see his benefits, and will also stimulate them to study their own prescriptions, so that they will no longer have to worry about the loss of good prescriptions due to concealment, and will also stimulate more doctors to study more kinds of diseases and obtain solutions for these diseases? ”

"What Xiahou means is that whoever makes up the skill has the exclusive right to this skill, and no one else, no matter who it is, cannot use it privately, let alone take this skill to himself." Imperial Physician Ling understood what Xia Hongsheng meant, pointed to the masonry under his feet, and said: "For example, if this masonry is made by me first, then this masonry is mine, and no one else can burn this kind of masonry without my consent." If anyone wants to burn this kind of masonry, they have to get my consent and pay me the corresponding money, if not, is it illegal? (To be continued.) )
